Spatz joins board of Voltea Inc

The former chairman and CEO of Osmonics Inc, Dean Spatz, has joined the board of Voltea, the UK
developer of capacitive deionization (CapDI) desalination.

Spatz is a chemical engineer and past or present member of the American Institute of Chemical
Engineers, American Membrane Technology Association, International Desalination Association
and American Water Works Association, and was on the board of directors of the Water Quality
Association. He is also a director of Sigma-Aldrich Corporation, a Fortune 1000 company.

"We are proud to have Dean on board and feel that his experience and knowledge will
be of great value in accelerating Voltea's growth", says Michiel Lensink, CEO of Voltea.

Voltea's award-winning platform technology CapD-I has numerous applications, from
water softening in domestic appliances to treatment of water used in industrial processes.

Initial investment in Voltea came from Unilever Ventures, followed in 2009 by leading
US water company Pentair. Rabo Ventures led an additional financing round in 2010.
